Concrete Specimen Grinding Machine

Concrete Specimen Grinding Machine

The Concrete Specimen Grinding Machine is an automatic system designed for grinding and polishing concrete cubes, cylinders, blocks, rock cores, natural stone, and ceramic materials. It is widely used in construction material testing laboratories where accuracy and repeatability are essential.

Specimens are securely mounted using locking stirrups for fast and accurate setup. A bench model is also available, featuring a hand-operated movable platform for precise positioning of cubes, cylinders, and rock cores.

Automatic & Efficient Grinding

The machine features a fully automatic grinding head with an end-of-stroke system. This allows bidirectional movement without manual operation, ensuring consistent and repeatable grinding results.

Multiple specimen types can be processed simultaneously, improving efficiency in concrete testing equipment workflows. A dry-grinding option is available through an integrated aspirator connector.

Precision Design & Durability

The abrasive head is motor-driven and provides radial movement in both directions. Vertical adjustment is controlled using a precision hand wheel with 0.05 mm increments, ensuring exact specimen preparation.

The fully protected column prevents abrasive dust from entering internal components, increasing durability and reducing maintenance. The rugged steel frame supports continuous use in demanding laboratory testing environments.

Standard Equipment Included

Each grinding machine system includes:

• Control panel
• Coolant and decantation tank
• Motor pump
• Standard abrasive grinding sectors
• Safety chip guard with automatic stop function

Diamond grinding sectors are available as optional accessories through concrete accessories and test equipment.

Available Models

• HC-2979.2F.3 — 220V, 60Hz, 3-Phase

Grinding Process

The grinding process uses a central grinding head with a horizontally movable specimen platform. The automatic end-of-stroke system ensures smooth movement in both directions, allowing consistent preparation of cubes, cylinders, and rock cores used in concrete compression testing.

Applications

• Preparation of concrete test specimens
• Grinding and polishing rock cores and natural stone
• Construction and geological material analysis
• Use in laboratory testing equipment

Safety Guidelines

• Always secure specimens using approved locking devices
• Wear safety glasses and gloves during operation
• Inspect abrasive components and coolant systems regularly
• Ensure safety guards remain in place at all times

These steps help maintain safe operation and long-term machine performance.

The Concrete Specimen Grinding Machine is a powerful and reliable solution for laboratories requiring precise grinding and polishing of concrete and rock specimens. With automatic operation, durable construction, and compatibility with Certified MTP concrete testing equipment, it delivers consistent and professional results for material testing applications.
